Related to dance, this needs feet moving! (7)
I believe the answer is:
treadle
'this needs feet moving' is the definition.
The definition suggests a singular noun which matches the answer.
'related to dance' is the wordplay.
'to dance' indicates anagramming the letters (letters must dance around).
'related' is an anagram of 'TREADLE'.
Can you help me to learn more?
(Other definitions for treadle that I've seen before include "Foot lever giving power" , "(Machine's) foot-control" , "Alerted (anag)" , "Foot-pedal" , "Pedal operating machine" .)
